It is also an object of the invention to provide a device of thisgeneral character including a pivoted jaw and a co-acting sliding jawtogether with means for c0nstantly urging the sliding jaw toward thepivoted jaw.

The invention consists in the details of construction and in thecombination and arrangen'ient of the several. parts of my improvedwrench wherein certain important advantages are attained and the devicerendered simpler, less expensive and otherwise more convenient andadvantageous for use,

as will be hereinafter more fully set forth.

The novel features of my invention will claimed.

In order that my invention may be the better understood I will nowproceed to describe the same with reference to the accompanyingdrawings, wherein:

The portion of the shank 1 extending within the recess 7of the swinging aw 5 is provided with a lateral extension 21 having itsperiphery con centric to the pin 8. The extension 21 snugly fits withinthe'inner portion of the structed in accordance with my invention isparticularly well adapted for use by reason of the conven ence andfacility with which it may be assembled and ope ated and it will also beobvious that my invention is susceptible of some change and modificationwithout niaterially departing from the appearance and spirit thereof andfor this reason I do not wish to be understood as limiting myself to theprecise arrangement and formation of the several parts herein shown .incarrying out my invention in practice eX- cept as hereinafter claimed.

I claim: A pipe wrench comprising a shank, a 1 aw pivotally engaged withan end portion of the shank, a slidable jaw mounted upon the r shank andeo-acting with the pivoted jaw, opposed walls of the bore of the slidingjaw being in divergence, the inner end portion of one of said opposedwalls being provided with teeth, the adjacent face of the shank beingprovided with teeth adapted to interlock with the first named teeth, alateral extension carried by the shank at a point remote from thepivoted jaw, said lateral extension being provided with a bore, a rodpivotally engaged with the outer end of the sliding jaw and extendingwithin the bore of the lateral extension of the. shank. and a springencircling the. rod and interposml between the outer end of theslidingjaw and the inner end of the lateral extension.

In testimony whereof I hereunto ailix my signature in the presence oftwo witnesses.
